SPECIFICATION forming part of Letters Patent No. 630,960, dated August15, 1899.

Application filed April 5, 1899. Serial No. 711,813. (No model.)

To all whom, it may concern: v

Be it known that I, JOHN WILLIAM WIL- sON, a citizen of the UnitedStates, residing at Pocahontas, in the county of Tazewell and State ofVirginia, have invented a new and useful Sash-Fastener, of which thefollowing is a specification.

This invention relates to sash-fasteners; and the object is to providean efficient and easily-operable device of this character involving anautomatically-operative bolt which is adapted to lock the sash in itslowermost or in its uppermost positions or to maintain the same at adesired place between these two extremes.

The device involves in its construction a rack and pinion connected withthe window and its casing, a hollow stud for rotatively supporting thepinion, a bolt supported by the stud for reci procation and adapted toproject into seats in the pinion and havinga beveled end, and means forturning the bolt to permit the release ofthe window-sash, so that thelatter can be raised or lowered, and the locking bolt is preferablyspring actuated and is operated by interlneshing gears connected,respectively, to the bolt and to a thumb-piece rotatively supported byacap or cover for the hollow stud that supports the pinion, and means isprovided for limitingr the movement of the thumb-piece, thereby toindicate positively the release of the sash when the saine is up ordown.

lVith these ends in view the invention consists in the novel combinationof elements and in the construction and arrangement of parts, which willbe hereinafter' fully described and claimed.

To enable others to understand the in vention, I have illustrated thepreferred embodiment thereof in the accompanying drawings, forming apart of this specification, and in which- Figure l is an elevation of aportion of a window sash and frame having the invention applied thereto,parts being broken away to illustrate theoperation of the fastener andthe latter adjusted to prevent an upward movement of the window-sash.Fig..2 is a similar view illustrating the fastener adjusted to permit ofan upward movement of the window-sash. Fig. 3 is a face view of thehousing or casing having its cover removed. Fig. 4. is a detailsectional view of the pinion. Fig. 5 is a detail perspective view of themeans for adjusting the locking-bolt. Fig. 6 is a detail perspectiveview of the plate or bar for holding the lockingbolt in position. Fig. 7isavertical longitudinal sectional view of the device.

The same letters and numerals of reference are used to designate likeand corresponding partsin each'of the several gu res of the drawings.

Referring to the accompanying drawings, B designates an attaching-platehaving oppositely-disposed lugs or ears (i, adapted to receive suitablefastenings whereby the device may be mounted upon 011e of the side railsof a window-sash. Intermediate of its ends this attaching-plate isprovided with a hollow outwardly-extending casingor housing 5, havingits outer end reduced in thickness, as at 4., to provide a hollow studupon which the pinion 2 is adapted to be rotatively mount-ed. Upon theface of the adjacent stile F of the window-frame there is provided asuitable rack 3, with which the teeth of the pinion 2 are adapted toregister during the vertical f movement of the sash, and the pinion isadapted to be locked against rotation, Whereby the sash may be held in apredetermined position.

Housed within the casing and the hollow stud is a transversely-disposedlocking-bolt 7, having its outer end beveled, as at 8, and adapted to bemoved longitudinally through a suitable `opening provided in the hollowstud 4, whereby the beveled end 8 of the locking-bolt may be engagedwith suitable seats or pockets 9, provided in the inner face of the hubof the pinion 2, whereby the latter may be locked. Located within thecasing 5 and projecting outward from the back thereof is an integral web10, which is adapted to form a bearing for the inner end of thelocking-bolt 7, and provided upon the inner extremity of the latter is asector 18, arranged upon one side of the web 10, opposite the beveledend of the bolt. A suitable transverse stop-shoulder 17 is provided uponthe locking-bolt'within the hollow stud et, and encircling the boltbetween said stop-shoulder and the web lO is a coiled spring 16, adaptedto IOO normally hold the locking-bolt in its extended position, with thebeveled end 8 projecting exteriorly of the stud l. lt will be noted thatthis stop 17 engages the inner wall of the hollow stud 4 and preventsthe locking-bolt from being projected too far beyond the exterior of thehollow stud, and the coiled spring permits of a slight inwardlongitudinal movement of the bolt when the window-sash is being moved.In order that the inner or sector end of the locking-bolt may be held inposition against the outer edge of the web 10, a transverse strap l2 isprovided, having its opposite ends bent up to provide shoulders 12, andthese shouldered ends of the strap are adapted to be seated in notches13, provided in the outer edge of the hollow stud at the opposite endsof the web 10, whereby the strap is seated transversely across thelocking-bolt and the latter is eifectively held in place. Fitted flushagainst the outer end of the hollow stud 4 is a circular plate 15, heldin place bya suitable screw fastening 14, eX- tending through the plate,the strap 12, and into the outer edge of the web 10, whereby the strap12 and the plate or cover are removably fastened to the hollow stud, andthe locking-bolt is effectively protected against the ingress of dirt,dac.

By reference to Fig. '7 particularly it will be noted that theperipheral edge of the coverplate 15 projects beyond the sides of thehollow stud 4L, overlapping the hub of the pinion 2 and convenientlyholding the same in place upon the stud.

In the operation of the device it will be understood by reference toFig. 1 that when the locking-bolt is projected into one of the seats 9in the hub of the pinion 2 the latter is locked against turning in adirection to the right, as the side of the bolt engages the upper wallof the seat 9, and in this position of the bolt the window-sash cannotbe moved upwardly. In order that the pinion may be released andpermitted to revolve, it is necessary to turn the locking-bolt axially,so as to dispose the beveled end of the bolt in the position shown inFig. 2,- when by reason of the beveled end 8 being disposed upwardly itis possible to raise the window-sash, as the pinion may then be turnedto the right,which movement will force the bolt longitudinally withinthe hollow stud and out of engagement with the rack 3.

To provide for axially turning the lockingbolt, as hereinbeforedescribed, an actuating mechanism is provided and consists of a stud 20,having at its inner end a sector 19, in mesh with the sector 18, carriedby the locking-bolt, andy provided with an operating thumb-piece 21 atthe outer end of the stud. The latter is mounted centrally through theplate or cover 15, and the sector 19 is located between the strap 12 andthe innerside of the cover 15, whereby said stud is mounted in positionand prevented from becoming disengaged from the sector 18. A circulardisk 2i is provided upon the stud between the thumb-piece 21 and thecover 15, against the outer side of which the disk is adapted to lit. Atsuitable points in Ithe peripheral edge of the disk there are providedtwo opposite shoulders 25 and 26, respectively, which are adapted toengage a suitable stop 23, provided upon the outer face of the cover 15in the path of said shoulders. lt will be apparent that by turning thestud 20 by means of the thumb-piece 21 the sector 19, meshing with thesector 18, carried by the locking-bolt, will turn the latter axially, soas to dispose its beveled end 8 in the desired relative position.

By reference to Fig. 1 it will be understood that the stud 2O has beenturned until the shoulder 25 has been engaged with the stop 23, wherebythe locking-bolt has been turned to disposeits beveled end downwardly,whereby the window-sash is locked against being raised. 1n Fig. 2 thestud 2O has been turned until the opposite shoulder 26 is in engagementwith the stop 23, whereby the beveled end of the locking-bolt isdisposed in a direction opposite to that shown in-Fig. 1, whereby onraising the window-sash the hub of the pinion will force thelocking-bolt longitudinally within the easing 5, out of engagement withthe seats 9, and thus the window-sash is free to be raised. In thislatter position of the locking-bolt it will be understood that the-pinion 2 is prevented from being turned in a direction to the left,whereby the windowsash will be held at any predetermined position.

The present invention provides an exceedingly practical and effectivesash-fastener, as the operative parts thereof are conveniently housedagainst the ingress of dirt, tc., and

IOO

being located wholly upon the inner side of the sash it is impossiblefor the fastener to be either removed entirely from the sash or unlockedfrom the exterior of the window.
